How do I turn off the Primary Menu system appearing at top of page?

Hi DIVI Help-
How do I turn off the Primary Menu system appearing at top of page? I would like the Primary Menu to just disappear upon scrolling down on a page. http://jgh.435.myftpupload.com/

Please advise.

Ok I removed the entire CSS Class for that row and now the Primary Menu jumped to 2 lines. I should've kept the code that was there. Was I only supposed to delete part of the CSS name under Advanced? Let me know if I was not supposed to delete the entire name and only part of it? Here is a link to the website - http://jgh.435.myftpupload.com/. We are using Library Style #9

 

Originally we had the text centered in the primary menu system right now it looks like it is pushing right.

 

Also how do I make it so that the text in the menu system is not ALL CAPs. For instance, FAQs has a small s in it in the Appearance < Menu and how it displays and yet it appears in ALL CAPs. Not sure where the CSS is for that but would like the DU Regular Menu text to appear the way the text is under Appearance < Menu.

 

I put 'free-regular-menu' back into the CSS Class on the Row Setting but that didn't help with returning the primary menu back to one line and text centered.
